One advantage is that pvmove allows you to keep the device online...
Right, that is pretty advanced. Good going.
We are also working on a feature ATM called “duplicate”. It allows
you to create a duplicate of any LV stack, create the duplicate where
you want, and even change the segment type in the process. For
example, you could move a whole RAID5 LV, or thin-p, in one go.
I think one important "trouble spot" is that there is no operation
yet(?) to create a duplicate of a PV that will not ruin the system
unless you do pvchange -u and vgchange -u ;-).
It took quite a bit of time for me to realize what was going on ;-).
Is PVMOVE supposed to be a backup task? I don't think so? How are you
supposed to back something up if you are planning to move your system to
a new disk?
